Subject aims expressed by acquired skills and competences

1. To characterize the basic acoustic problems and recognize these problems in engineering practice. 2. Explain the principles of acoustic measurement methods, describe their algorithms and discuss their advantages and disadvantages. 3. Apply theoretical knowledge to solving practical problems, interpret the results, modify the solution procedure. 4. Analyze and evaluate the results of acoustic measurements and numerical simulations, predict treatment in applied procedures.

Summary

Students will learn the basic procedures of the experimental acoustics and obtained experiences can virtually test and verify on the measurements in the acoustic laboratory, i.e. semi-unechoic chamber. Selected patterns of acoustic problems the students will verifie by mathematical simulation using numerical methods.

Way of continuous check of knowledge in the course of semester

Student will elaborate several technical reports, thematically linked to current measurement issues. The form and level of elaboration of reports is one of the evaluated criteria for completing the course. Completion of the course is in the form of an examination.

E-learning

Other requirements

The exam has a practical and theoretical part. In the practical part the student solves numerical tasks in the field of technical acoustics. Foreign students can in individual cases complete the course individually in the form of a semester project.
